.SH NAME
DROP TABLE \- remove a table

.SH SYNOPSIS
.sp
.nf
DROP TABLE [ IF EXISTS ] \fIname\fR [, ...] [ CASCADE | RESTRICT ]
.sp
.fi
.SH "DESCRIPTION"
.PP
\fBDROP TABLE\fR removes tables from the database.
Only its owner may destroy a table. To empty a table of rows
without destroying the table, use DELETE [\fBdelete\fR(7)] or TRUNCATE [\fBtruncate\fR(l)].
.PP
\fBDROP TABLE\fR always removes any indexes, rules,
triggers, and constraints that exist for the target table.
However, to drop a table that is referenced by a view or a foreign-key
constraint of another table, CASCADE must be
specified. (CASCADE will remove a dependent view entirely,
but in the foreign-key case it will only remove the foreign-key
constraint, not the other table entirely.)
.SH "PARAMETERS"
.TP
\fBIF EXISTS\fR
Do not throw an error if the table does not exist. A notice is issued 
in this case.
.TP
\fB\fIname\fB\fR
The name (optionally schema-qualified) of the table to drop.
.TP
\fBCASCADE\fR
Automatically drop objects that depend on the table (such as
views).
.TP
\fBRESTRICT\fR
Refuse to drop the table if any objects depend on it. This is
the default.
.SH "EXAMPLES"
.PP
To destroy two tables, films and 
distributors:
.sp
.nf
DROP TABLE films, distributors;
.sp
.fi
.SH "COMPATIBILITY"
.PP
This command conforms to the SQL standard, except that the standard only
allows one table to be dropped per command, and apart from the 
IF EXISTS option, which is a PostgreSQL 
extension.
.SH "SEE ALSO"
ALTER TABLE [\fBalter_table\fR(7)], CREATE TABLE [\fBcreate_table\fR(l)]
